What is the model / serial # of this engine ???---------An 83 model would have 2 switch boxes on the side of the motor !!
 
The blue wire needs to be replaced. There may be a problem w/the switchbox, stator and voltage regulator.
 
its a thunderbolt and s number is 6263018 the box that has the crisp wire has 3 coming out of it a red,black and a white with a black stripe
